I've read all of the other questions on this error and frustratingly enough, none give a solution that works.

If I run pip install sentencepiece in the cmd line, it gives me the following output.

 src/sentencepiece/sentencepiece_wrap.cxx(2809): fatal error C1083: Cannot open include file: 'sentencepiece_processor.h': No such file or directory
      error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\BuildTools\\VC\\Tools\\MSVC\\14.16.27023\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2
      [end of output]

I'm running python 3.10.1 and pip 22.0.3 .

*I have the following Microsoft Visual C++ programs on my windows machine,which I've just done a fresh install of as it was complaining of not having a particular C++ program. MS VC++

I've even added the .exe file to my PATH variables but still I get the same error.

Am I missing a particular Microsoft program on my pc?

pip windows python

I haven't seen this problem in Windows, but for Linux, I would normally reinstall Python after installing the dependencies (such as the MSVC thing). In that case this is especially helpful because I'm often rebuilding (compiling and other related steps) Python/Pip.

Could also just be an error specific to the module and Python version combo you're trying.

From a discussion in the comments:

I have the pyenv-win version manager, so I was able to create venvs and test this for you. With Python 3.10.2, it fails; with Python 3.8.10, it's successful. So, yes, reinstalling does seem to be worthy of your time.

With python3.10

On Windows: First, install vcpkg and install sentencepiece:x64-windows-static

copy the header and lib files from vcpkg/installed/x64-windows-static/include and lib to

C:/Program Files/python310/build/root/include and lib

This should work as the setup.py install expects the library in a ..\build\root\lib directory.

As the C:\Program Files\python310\lib is in the /LIBPATH, the resulting ..\build\root\lib will point to the sentencepiece.lib

If still encounting errors, then set the INCLUDE and LIB environment variables so that the cl.exe , which is called from pip install sentencetransformers finds them.

People having windows+python 3.10 env, here are exact steps to install it via vcpkg.

Other instructions are covered in zweistein's answer.

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install sentencepiece:x64-windows-static
